Every module belonging to a single mainline module family will be
hidden from make, except the one which has been flagged using
apex_contributions
Details
- Introduce a new `source_apex_name` property to prebuilt_apex and
override_apex. This property will be used to identify the source
equivalent of a prebuilt soong apex module.
- Create an N-ary tree from source to prebuilt(s). The tree wil be
rooted at the source module.
- In a subsequent mutator, visit every node in the tree(s). Query
apex_contributions and store the handle of the node which is "active"
(if any)
- In the same mutator, do another pass over the tree. Invoke
`HideFromMake` on every node which is not "active". The two-pass
approach is needed PrebuiltSelectionInfoProvider does not know about
the inter source-prebuilt dependency, this dependency can only be
known by doing a graph walk of the N-ary tree.
Some tangential implementation details
- Each prebuilt apex has an internal deapxer module that is responsible
for generating the deapex ninja rules. The name of this internal
module uses the BaseModuleName (without the prebuilt_ prefix). Since
we can have multiple prebuilt soong modules in trunk stable, change
this to follow the name of the prebuilt module in order to avoid name
collisions. Update existing unit tests accordingly

dexpreopt of apex system server from prebuilts involves three soong
modules
1. prebuilt_apex / apex_set
2. an internal deapexer module created by the prebuilt apex
3. java_import/java_sdk_library
(3) acts as a shim for the deapexer to set the dexjar extracted from the
prebuilt apex. This methodolody requires a 1:1 correspondence across the
three modules
This breaks down when we have multiple versions of the same prebuilt
apex in the tree. In preparation for this, move the dexpreopt
processing from (3) to (1). Each prebuilt_apex will create the necessary
rules for dexpreopting the jars deapexed from itself. In the future,
apex_contributions will be used to pick which service-foo.{odex|.vdex} to
install depending on which prebuilt apex is selected.
Implementation details
- Embed dexpreopter in prebuiltApex structs so that this module type can
register the dexpreopt rules. Since a single apex can have multiple
system server jars, this also requires creating an additional scope in
dexpreopt.go to prevent name collisions
- Add the dexpreopt modules as required in initApexFilesForAndroidMk
- Add the depreopt modules to androidMk in AndroidMkEntries. Drop the
equivalent from java_import and java_sdk_library_import

After this change, if "profile_guided: true" is set, profile-guided
compilation will be enabled for the jar and the ".prof" file next to
the jar in the APEX ("javalib/<name>.jar.prof") will be used as the
profile when dexpreopting for the prebuilt APEX.

After this change, if profile-guided compilation is enabled for an APEX
system server jar, the profile will be installed next to the jar with
the ".prof" suffix, ("javalib/<name>.jar.prof"). This file will later be
used by odrefresh and dexpreopt from prebuilt APEX.

This CL updates platform_systemserverclasspath,
systemserverclasspath_fragment, and
prebuilt_systemserverclasspath_fragment to write entries for
STANDALONE_SYSTEMSERVER_JARS to systemserverclasspath.pb. A new property
`standalone_contents` is aded to `systemserverclasspath_fragment` and
`prebuilt_systemserverclasspath_fragment` to list the standalone system
server jars in the APEX, and entries will be written to
systemserverclasspath.pb accordingly at build time.
To add more context, these entries will be consumed by derive_classpath
in order to generate an environment variable
PRODUCT_STANDALONE_SYSTEM_SERVER_JARS. The environment variable will
then be comsumed by odrefresh to determine what jars to preopt on early
boot.
Note that the variable should not end with "CLASSPATH" because the list
is not used by runtime as a classpath. It is just a colon-separated list
of jars. System server loads the jars separately with paths hardcoded in
the code.
Bug: 203198541
Test: manual -
1. Add some jars to PRODUCT_STANDALONE_SYSTEM_SERVER_JARS
2. Add some other jars to PRODUCT_APEX_STANDALONE_SYSTEM_SERVER_JARS
and standalone_contents.

4. Flash the image to a device.
5. adb shell echo \$STANDALONE_SYSTEMSERVER_JARS
6. See the correct list of jars.

The source of truth for what jars are in BOOTCLASSPATH and
SYSTEMSERVERCLASSPATH is make; adding a classpath fragment in soong
with a new jar in the contents without having it declared in make
is wrong (excluding test apexes).

This must always be true for updatable apexes, but is not necessary
for non-updatable apexes like com.android.i18n.
In a follow up this will be used to figure out whether apex boot jars
should be bundled into platform_bootclasspath.
